... 5% are described as “rejected.” It is wise to keep in mind that there is nothing special about the 5% value other than the fact that most people agree on using it. Hypothesis can be “rejected” or “not rejected,” but this is not to be taken as disproving or proving the statements. The proper use of s ...

... Some residuals will be positive and some negative, so adding up all the residuals is not a good assessment of how well the line fits the data. If we consider the sum of the squares of the residuals, then the smaller the sum, the better the fit. The line of best fit is the line for which the sum of t ...
